Text of Note

There is a good understanding of surface chemistry in vacuum, but not for materials in real environments. Fully understanding the surface properties of materials in ambient environment plays an important role in realizing their potential applications toward other fields of chemistry. This dissertation focuses on how the environment alters the surface chemistry and properties of different materials. My work has three parts: graphitic carbon, rare earth oxides, and graphene fibers. Various surface analysis techniques are utilized to investigate and characterize the relevant surface properties of carbon and rare earth oxide materials and their contaminations due to exposure in real environments. Results from such work is further used to probe and manipulate the effect of surface chemistry on the adhesion chemistry of graphene fibers, ultimately changing its respective mechanical properties.
